Patent EP-0835025-A3 (EP)
Inventor: KAKUTANI TOSHIAKI
IPC: B41J2/52
Filed: 1997-10-01
Abstract: In a printer for printing an image by a distribution of dots
having different densities per unit area or dots having different
hues, the structure of the present invention accurately determines
the on/off state of the different dots and ensures high quality
printing. Recording ratios Rn and Rt of deep dots and light dots
corresponding to input tone data DS in a target pixel are read from
a map representing the relationship between the recording ratios
and the tone data. The systematic dither method is adopted to
determine formation or non-formation of a deep dot in the target
pixel. This method compares the recording radio Rn of deep dots
with a threshold value Dref corresponding to the target pixel and
read from a threshold matrix TM. In the case where a deep dot is
not formed, the recording ratio Rt of light dots is corrected by
adding the recording ratio Rn of deep dots and subsequently
compared with the same threshold value Dref to determine formation
or non-formation of a light dot in the target pixel. The structure
of the present invention uses only one threshold matrix to realize
desired recording ratios without causing any overlap of deep dots
with light dots. This structure is also applicable to dots having
different hues. In this case, one threshold matrix is used to
determine the on/off state of dots having different hues without
causing any interference of the different hues.

Abstract: A swath printing system (210) such as multi-colour inkjet
printing which uses lower resolution printheads (120-126) of
at least 300 dpi nozzle spacing to achieve high resolution
output of at least 600 dpi addressability in both the X (media
advance) and Y (carriage scan) axes. Synchronized depletion
masks for area fills and edge enhancement is provided which is
plot independent and prevents drop overlap. It is especially
suited for multi-pass print modes since each row has a
balanced number of pixels, and there are no rows which have no
"on" pixels. The depletion includes separate depletion masks
and rules for edge enhancement as compared to area fills.
Each colour plane is depleted separately, but subject to the
same depletion rules and masks. A separate depletion step
provides for narrowing the vertical and horizontal dimensions
of the figure to be printed.

Abstract: There is provided a data exchange system for line-exchanging data
transmitted from a plurality of control circuits, in accordance with exchange
information, characterized by a plurality of memories (2-1 to 2-n) each of which
stores data transmitted from an associated control circuit (1-1 to 1-n), a
designator (4) for providing each of the memories (2-1 to 2-n) a designation about
an area in an associated memory (2-1 to 2-n) in which the data is to be written,
and a reader (5) for reading out data written in the designated area in the
associated memory (2-1 to 2-n). The data exchange system makes it possible not
to include a line exchange circuit which was absolutely required for a conventional
data exchange system, and which was a major factor for keeping the system in a
large size. Thus, the invention provides a data exchange system smaller in a size
than conventional ones.

Abstract: In an optical disk, data are recorded by using a
hierarchical file structure in which a frame (F n ) is composed of
digitized data, a packet (P m ) is composed of at least one frame, and a
pack is composed of at least one packet. In this structure, the
pack is composed of an integral number of packets (P m ), each packet
being completed, and each of the packets is composed of an
integral number of frames (F n ), each frame being completed. Therefore,
there is no possibility that one frame is assigned over two or
more different packets and one packet is assigned over two or
more different packs. Since an integral number of frames are
assigned in each packet, when a packet header (11) is detected,
reproduction of data can be carried out from the beginning of
each packet.

Abstract: A double column cryogenic air separation system is operated to increase boilup

the vapor stream (213), and introducing the resulting expanded stream (223) into the
lower pressure column (29). Operation in this mode increases oxygen recovery at a
given rate of compressed and purified air feed or reduces the amount air feed required
to produce a given rate of oxygen product. Argon recovery (313) can be integrated
efficiently with the intermediate pressure vaporization (211) and work expansion (221)
steps.

Abstract: A method and an apparatus for a multibeam phased array antenna transmission based on
heterodyning to produce the RF transmission signals with appropriate phase shift and
thereby reducing the effect of certain space constraints in the confined area of the
transmitter as higher and higher frequencies of transmission are employed. In the present
invention, RF signals at an intermediate frequency, not the ultimate frequency of
transmission, comprise the signal frequencies of a beam forming network which provides
input to a multiplexed power divider (20). The power divider outputs the phase shifted
signals to an input at each of a number of multiplexed combiners (22). The output of
each combiner is fed to a mixing device (23) which then shifts the input frequency to a
higher frequency, using an appropriate local oscillator signal. The mixer outputs are
coupled to separate power amplifiers (26), whose outputs are fed to the elemental
radiators (33). The use of a lower primary frequency in the power divider and the
combiner stages permits the use of conventionally sized components, rather than miniature
elements normally associated with millimetre-wave circuitry.

Abstract: A method and apparatus for mapping physical addresses to virtual addresses in a computer
system such that thrashing is minimized and performance is enhanced is provided. The computer
system includes a storage device such as a cache for storing data from a subset of pages of a
physical memory. Each page of the cache is referred to as a cache page, and has an associated
cache page address. Physical addresses are selected for mapping to a virtual address in part based
on the value of a cache page address related to or substantially included in the physical address.
Translations of virtual addresses to physical addresses may be associated with individual
processes. When virtual address translations are formed, physical addresses are selected such that
the associated cache page addresses are substantially evenly distributed both within the process
associated with the translation and among all virtual address translations. With such an
arrangement, because cache page addresses are substantially evenly distributed within each
process, intra-process thrashing is minimized. In addition, because cache page addresses are
substantially evenly distributed among all virtual address translations, inter-process thrashing is
also minimized. By minimizing the occurrence of both inter-process thrashing and intra-process
thrashing, the overall performance of the computer system is improved.

initialization and runtime code. Upon initialization, the communication initialization code is

memory, such as System Management Mode (SMM) memory. The runtime communication
code is executed in response to an interrupt to the secure memory. If the secure memory is
SMM memory, then a SMI will trigger the execution of the communication code. The main
memory is not accessed to execute the runtime communication code.
